In the article “Safety and Efficacy of an Injectable Extracellular Matrix Hydrogel for Treating Myocardial Infarction,” some numbers for the rat biocompatibility study were listed incorrectly. Animal numbers and lesion sizes in the first paragraph of the section “Myocardial matrix is biocompatible and biodegradable” have been changed. Figure 5 has been corrected to reflect that no animal experiments were performed for NDM at day 7; PMN and saline groups remain unchanged. The full text and PDF have been corrected.
